Design of High-Enthalpy Premixed Supersonic Heater and Experimental Study of Detonation
Bibliographic record
Abstract
In order to study unsteady process of shock-induced combustion and detonation of incoming flow at a high static temperature, a new facility was devised to produced highenthalpy premixed continuous supersonic gas, of which the static temperature was up to 700K. This novel design method integrate the mirror Laval nozzles into combustion heater. The premixed fuel was injected into the supersonic flow from special angle through several arrays of orifices in the nozzles in the expanding position, which will enhance the mixing of the fuel into the supersonic flow and weaken the disturbance of incoming flow. Some pressure transducers and a thermal couple were mounted on the mixing segment for confirming whether pre-ignition was happened. At last, the unstable processes of shockinduced combustion and detonation caused by fixing a wedge with 20 degree angle in the supersonic flow were investigated in detail with the help of high speed schlieren photograph, along with the unsteady behaviors of detachment detonation. The result shows that two metastable states, that is, shock-induced combustion and detachment detonation, exists simultaneously in current experiment and the transition process between the two states is very quickly.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
